REGULATING DEVICE FOR INTERNAL-COMBUSTION ENGINES.

Application filed October 11, 1919.

309 McL-achlan Bldg, lVashington, in the.

District of Columbia, have invented certain new and useful lmproven'ients in Regulating- Devices for Internal-Combustion lilngines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same,

My nvention relates, broadly, to regulating devices for internal combustion engines; and, especially, to an apparatus for control-'- ling the supply of vapor and air, creating a "inotor-brake by air supplied to the engine,

rendering the mixture in the engine incombustible by supply of excess air, setting an alarm to be operated by the engine when it is intended that the engine shall not operate, and cutting out the ignition devices.

I propose to control the distribution ofthevapor and air, the creation of a motor-brake,

the destruction of the combustible quality of the mixture supplied to the engine, to provide an alarm which shall be operated upon any attempt. to start the engine when it is intended that the engine shall not operate,

and ignition controlling devices, all in a sin gle compact device which may be applied between the dash board and lnstrument boa rd. and shall be governed by a direct acting single means.

I accomplish these and other objects by a ported cylinder controlled by a piston-valve through a hand-operated stem having devices which will enable me to secure what may be termed a positive micrometer control. By these means I admlt vapor to the intake manifold to enrich the gas comlng from the carbureter, admit air to lean the mixture go-.

handle of the stem connection with the holof atmospheric air as to create a motor brakein the engine while running down hill, for

example, and also destroying the combustible quality of the mixture, thus serving as a lock to the motor by preventing a propelling operation. Upon a fourth and final move-' ment of the piston-valve, whistles are made operative to serve as a warning in case of an attempt by an unauthorized person to start the engine, and at'the same time the device cuts out the ignition circuits through the operation of pins carried by the whistles.

Figure l isa diagrammatic view illustrating my invention applied to an automobile and indicating thearrangement of the parts of my vdevice'with respect to the radiator, engine, etc.

This figure also illustrates the posl- .-.tion in which the quantity of air entering the engine will destroy combustion and lock the car, that is, prevent its being started by the ignition devices The supply of vapor is automatically cut as when the engine'stops firing by a vapor 'tra to prevent the admission of moisture in suc case. I

Fig. 8 shows the final position or" the parts with thepiston-valve farther removed from the discharge end of the cylinder whistles, drawn against the sides of the cylinder and in communication therewith. In this position also a contactpin carried .by a whistle is brought against the magneto pins "to' ground the circuit and the contact pin is moved out of thebattery circuit to break it, thus cutting out the ignition devices.

While in this position any attempt to operate the engine will result in a suction through the cylinder of my device created by the intake stroke of the engine piston,

and by this suction air will be drawn through the whistles sounding an alarm as long as there is any operation of the engine.

' Fig. 9 isa section on the line'9-9 of Fig. 8 to show the details of the whistle connections;

Fig. 10 is a detail showing the manner in which the valve stem is readily controlled and its different movements indicated;

Fig. 11 is a section of the trap shown in Fig. 1 as located upon the head of the radiator.

Fig. 1 also shows'the lock applied to the stem; and Figs. 2 and 3 the relation between the circuits and the contact pins carried by the whistles.

Figs. 2 and 3, as before stated, show my device in the position when the car isnot in use, Fig. 1 further showing the application of the lock or padlock over the threaded .part of the stem shown in Figs. 2 and In that position the whistles are. drawn that there is no air inlet between the cylinder and the body of the whistles, and any vwhistles by'the engine.

here that the lock to compress the air in the engine cyl-' and the air entering must be drawn in throughthe It may be. observed must be takenofl' before the device can be operated and that the mere fact of the driver having the lock' on his person indicates. at

once that the device has not been locked to prevent unauthorized use.

fold. 27 is a pipe lea ing from my device to a trap 28 attached to and communicating Withthe water head 21 of the radiator.

29 is the main-body or cylinder ofmy de- Vice which is attached between the customary dash-boardand, an instrument head 30 by means of a'flange or plate 31.

32 is a threaded opening on the discharge end of the main body or cylinder of my device, to which is secured, as indicated, an end of the feed pipe 26. 33 indicates the port to which vapor is fed from the radiatorthrough the pipe 27 34: indicates atmospheric ports,

one on each side, leading into the cylinder 29.

It will thus be apparent that there are two ports 33 and 34 leading into the cylinder and a discharge opening 32 through which the vapor or its mixture with atmospheric air may pass to the intake manifold there to be mixed with-the gas being introduced from the carbureter, or to be supplied in such quantities as to form a motor brake when the car is running doWn-hilhfor example; and a lock when the engine is at rest by rendering the mixtureincombustible so that the air, vapor and gas may be simply an inoperative mixture incapable of starting the motor.

Within the cylinder there is a hollow piston-valve 35 withports 36 on opposite sides and a slot 37 taking over a pin 38 having a screw head to hold the piston-valve centrally and in register with the atmospheric air ports 34:. The piston-valve is so arranged guide 4.0 when the stem is drawn back and forth. The stem 39 is reduced at the lower that it may cover all the ports admitting I end at 41 and passes through a collar 42 on the head of the hollow piston, being secured by a button or disk on the bottom of the stem. This provision e'nablesthe stem to be turned freely in the head of the hollow piston and to operate the piston in longitudinal directions.

It will be observed that by this positive micrometercontrol I have provided for the finest adjustments.

On the side of the stem is a key 44 adapted to take into a slot 45 in the guide 40.

The stem has a hand-wheel or control knob 46 for convenient operation, and on the hand-wheel is a mark of'some character, as, for example, that illustrated at 4:7. This mark is arranged in line with the key 44.- The operator knows this and being advised of the exact turrr required may. bring the key into registerwith the slot 45 so that the piston-valve may bedrawn' to its extreme position against the head guide 40, the key 44 entering the slot 45.

A8 designates a threaded projection (see Fig. 10) on the flange or head 31 havin a recess 49 on the bottom. -In the. threa ed pro ect1on operates a screw 50 w1th a c1rcular enlargement at the bottom operating against a spring 51 to control the pressure of an anti-friction ball 52 running in spirah grooves or threads 53 on the stem 39, so that the turning of the stem may regulated.

In this device the 133 11552 will prevent a too easy rotation of'the stem and at the same time will operate as an anti-friction ball to prevent an undue stiffness in the rotation of the stem 39. I have provided foran exact relation between the needs of the engine for vapor and air and the size of the ports and their regulation. In running the engine, I secure a precise adjustment by the arrangebe easy and yet ment of the stem and the piston-valve while at the same time I can, to meet an emergency, draw out the valve to open the atmospheric .ports to create a motor-brake; and

\ before starting I can quicklyp ish in the piston-valve, the stem 39 in this oaserec-ipro eating, the ball 52being pushed up as the threaded stem forces its way through .the' guide 40. In drawing back the-knob 4:7 in

an emergency the piston-valve first brings up with the stop 44 against the bottom ofinder, 63 arms on passage about the groove thus giving a sharp click to indicate to the driver that he has made the desired turn of\the control knob.

" These notches 520 are shown in the second and fourth turn, the next turn being indicated to the driver by the stop against the bottom of the head to.

A sn'i'all rotation or reciprocation of the stem 39 of the piston-valve 35 secures the desired result. I may set the screw 50 conv dd comlng trolling the pressure of the ball 52so .that

the device may be easily adjusted for all kinds of cars and yet so that thestem 39 may be pushed .and drawn out rapidly against the resistance of the spring-pressed ball,as before indicated. The sound indicating provision is especially-useful for night driving. It may also be observed that in time the position that the stem 39 or the control knob a6 assumes will become a suiiicient guide to one familiar with my device. N

The vapor trap, 28, shown in detail in Fig.- 11 is divided by a central seat 545 into two chambers 55 and 56. The valve seat is perforated, as illustrated at 57, two of the perforations there being illustrated, it'being understood that there may be any number. 58 represents a valve controlling the perforations and having about its stem a spr ng 59 bearing at the other end against a disk 60 governing the opening to the air in the bottom chamber. ('31 is a pipe leading into the water chamber of the radiator.

IVhen the vapor port 33 is open" to the cylinder 29 the vapor passes up through the perforations and through the feed pipe 27. lVhen the port 33 is closed, the valve .58 seats to close the perforations 57 and opens the bottom chamber to the air by. the consequent lowering of the disk 60, thus permitting the escape of condensed moisture.

62 represents opposing ears on the cyleach whistle body embracing-the perforated ears on the cylinder body and 64: pins which pass through/the arnis and ears so that the bodies of the whistles,

65 and G6, are swiveled being drawn together when permitted by a spring 67. Each wlnst-le bears a cam 68 adapted to enter the opposite atmospheric port 34: when the 1101- low piston is drawn back uncovering it. Thus, when the the cams 68 will begin to slide off the walls of the piston-valve, as shown in Fig.- 7, and willfinallv completely enter the cylinder atmospheric ports are open when the piston is drawn back to the position shown in Fig. 8, permitting the spring 67 to bring the properly formed walls of the whistle bodies tightly against the cylinder body registering the whistle with the air ports of the cylinder. The whistle is composed of a many port-ed disk 69 over which turns a ported revolving disk 70 centered-and secured to a rotor pin 71 with bottom of the stem guide 40.

circuit." In the operation of my device when the I whistles are drawn close against the cylinder the pins 76 and 77 are brought over the board 79 so that the pin 76 closes the magneto circuit at 80 grounding it through the' apparatus. At the same time the pin 77 is taken away from the battery circuit 800 breaking the circuit, which is closed when the whistles are again forced. away from the cylinder intothe positions shown, for example, in Fig. 7

By this means it will be observed that I do away with the customary switches and substitute for them in this compact arrange ment of parts the pins 76 and 77 carried by,

apartof the apparatus which is intended to be brought into operation at the time necessary to break the battery circuit and similiarly dispose of the magneto circuit, in thiscase by grounding the circuit.

- 7530, as shown in Figs. 1 and 8 andindicated in Fig. 2, represents a lock which can not be applied until the final movement away from the cylinder is had because it is of a form to just fit between the cone base of the control knob 46 and the extension of the guide 40 receiving the threaded section 53 ofthe stem. This provision serves to remind the driver that the whistles are not set until the control knob is in the final position with the piston-valve fitting up against the The pushing in of the stem 39 carries the piston-valve 35 'down against the whistlecams 68, )ushing them out, destroying the closure between the whistles and the-cylinde'r 29 and closing all the ports. Having reached that position shown in Fig. 5 the driver draws up the piston-valve admitting vapor to the cylinder 29 through the inlet 33. Another or second turn, as in Fig. 6, draws up the piston-valve partially open-' ing the ports 34: admitting atmospheric a r to-be combined with the vapor entering the cylinder through the port 33 so that when,

running ordinarily, sufiicient air maybe admitted to render thecombustion mixture lean, thus, in accordance with known principles, saving the gas, giving more power and rendering the enginemore eflicient. If

.now another and third turn be giventhe stem, the piston, as shown'in Fig. 7, will open far enough to permit the whistle cams to start inward. through the portsin the piston-valve,- the piston-valve still further uncovering the ports 3% to admit such quantities of. air as to operate as a motor brake,

the pistons of the engine operating against such quantities of a r and gas as to retard the engine, an operation known to be cspecially effective-when running down hill. I

This manner of running down-hill, dangerous in ordinary cases, is rendered entirely safe by my device.

hen the fourth or final turn of the stein is given the parts will be in the position shown in F ig. 8 as before stated. The whistles have closed against the cylinder 29, the ports 34 are now entirely uncovered and atmospheric air is continuing, as in Fig. 7', to enter in such quantities as to render impossible in any event the combustion of the fluids entering the engine cylinder. Furthermore, at this time the magneto 1s not in i one side the pin7 7 of this circuit.

Fig, 8, in fact, is Figs; 1 and 2 partially in section, but with the lock applied over the stem. When the lock is removed the stem and the connected piston-valve may be at once pushed into the position shown in Fig. 4 ready for the starting of the engine.

hen the motor brake is applied in running down hillit is ordinarily inadvisable to also apply the whistles though if desired they could be applied to operate as ordinary service whistles. To prevent the operation of the whistles while at the same time getting the' full supply of air to operate as a motor brake and to cut off the ignition, I have provided the key 44 on the pistonvalve 35 Which, in this position of the parts, abuts the head 40 as shown in Fig. 7. When it is desired to have the whistles come into position close against the walls of the cylizedattempt to start the car, a turn of the control knob approximately 45 to the left,

out farther and finally fit snugly against the 1 'inder 29 to operate in caseof an unauthorbottom of the guide'head &0, completely opening the ports 13& and permitting the whistle-cams 68 to enter the ports-34 and the spring 67 to bring the whistle-bodies up into 95 service, grounding having be n Q 'plislied by the moving of the pin 76 on tl1e whistle-bodies into, contact with the close and practically air-tight connection withthebody of the cylinder 2-9, the position necessary for their operation as sirens.

-' 1,It.willbe observed that in this regulating deviceI provide simply by different movemeritaiirst, for admitting moisture from the ra'd1atoir of the automobile to the intake manifold when the motor is in operation in quantities to suit the exact conditions of weather or-; load, and when the motor stops firin" I immediately check the vapor flow 'shouId the'contro1 remain open in the main bod of my device by the"vapor trap set in t 1e connection between the radiator and my device, thusreventing, the admission of moisture into the engine while idle. I also .provide for admitting extra atmospheric air'fso-that' if the supply coming from'the carbureterishould be rich enough it may '20 "ab'sorb extra air thus effecting a saving of fuel and-at the same time increasing the en Y'ne speed under light'loads. Again, by

' switch construction and of the ordinary choking device].

I have adjusted the vapor port with reference to the carbureter admission so that the supply of mixture is set for all occasions; and it is provided that if the supply be at first a little richer than is needed for ordinary running ,so that the car may be readily started, the operation of my regulating device 'will leanthe mixture as drawing raw desired. v t

' In my device I avoid'also the danger of and vaporized gasolene through the carbureterinto the combustion chambers of the engine and forcing it into the crank casewhe're it is mixed'with the lubricating oil and destroys the qualities of the lubricant, causing burnt out bearings and scorched cylinders, and making it impossible for the operator to determine the lubricating value of-the oil in the crank case. I also, by the same device, provide for the introduction of such quantities of air as to serve to prevent-the combustion of the fluids in the en inc, and at the same time cuttin out the ignition circuits by the ac- ,tion 0 the pins-carried by the Whistles. At

this time the ,whistles are in position .to operate as sirens. These will give a quick sharp alarm diflerent from any other signal. Itshould be observed that sound waves can 'not be produced by other than siren constructions when operating by suction as these Waves pass into the body of the device and are smothered with any other construction.

The connection between the piston-valve,

and its stem is such as to permit the pistonvalvc to'be either moved gradually to secure the control desired under ordinary circumstances, or to permit the piston-valve to be drawn back instantly permitting the flow of atmospheric air to create a motor-brake in the, engine cylinder, cutting oifthe ignition device and bringing-the whistles into communication with the air passage to the engine, so that, for example, if in runnin down hill the brakes should be disconnecte the motor-brake can be quickly a plied and at the same time the alarm-soun edby the engine, turning under the momentum of the car. In such event if the driver should abandon the car and its momentum should carry it down hill, the alarm would be'oonstantly sounding and the motor-brake applied.

It is a peculiar feature of my invention that the whistles are not operated or sub-- I ect to operation independently of the operation of the engine. When the en 'ine is inoperative they cannot be blown heedlessly or in a manner to annoy the public but can only be operated by an unauthorized-attempt to start the engine. This is particu-' larly important because the object of these whistles is 'to give notice 'to -the police or others in preventing the theft of a car. The whistles have a distinctive, sharp, rolling sound due to their operation as siren-whistles which at once attracts attention and gives immediate and continuous notice of the Q 7 event as long as there is any attempt to operate the n'iotor, this peculiarity or sound bemg due to the well known variations in the suction in such case.

In brief, my arrangement of a ported cylinder with a ported, hollow piston-valve is the most ecconomical construction for a device of this character, and. at the same time, by the addition of my: specific devices,

the most eiiective. The parts are few, their operation is all'in two directions, back and forth, and thewhole device takes up a small space. I urthermore, I secure in, a most economical manner the control of .the whistles by the same part which governs the vapor and air ports andby these movements I also control the ignition sothat in reality from the control knob alone-all the" actions or regulation are governed-the admission of-vapor, the subsequent admissionof atmosphcric air, theformation of a .motor brake or look through the operation 'oflarge ualr tities of-airin the engine, the setting o the whistles and the cutting off of the ignition device. l

It will be observodthat addition the structual arrangement of the air-and vapor regulating parts I have combined with these I refer to this again to emphasize the fact that I- have brought the ignition-control; into this combination and nto this small" parts the control of the ignition devices, have placed the alarm in communication with the air supply passage and have, prothe operation'of the whistles ofthev alarm.-

space so that all the regulating parts may be broughtclose to the operator. and so that any attempt to destroy the device can' only .result in rendering the engine inoperative.
